ROCKBROS Suction Cup Bike Rack Quick Release Aluminium Alloy for 1 Bike

Just took it on a 3 hour one way trip up north and it did great. I was going 80mph almost the whole time.

This rack is FANTASTIC as long as it doesn't come loose or un-suction during a long ride... time will tell on that one. So far it seems very sturdy.. .with my bike on it I can pull on my handlebars and the entire car shakes which is great! The bike does sway a bit on turns and bumps but I guess that's to be expected. My only worry is that it sways too much? The way its designed it seems that each time it sways it might actually push the suction on one side down further! As one side pull up the other is pushed down so.... NOTE FOR PEOPLE WITH THRU AXEL WHEELS/FORKS - I have a 15mm x 115mm Thru axel measured at REI from post to end of threads and so I needed an adapter. When asking RockBros AND REI which measurement they are using they said the FULL length of the axel stem......... this is incorrect, the measurement is the DISTANCE between your forks or the Axel stem measurement NOT INCLUDING The threads. Needless to say my 15 x 115mm thru axel works with the 15mm x 100mm adapter. I went crazy trying to figure out if I needed a 115mm axel adapter but just decided to try out the 100mm. It obviously worked and now I can transport my bike!! Note: the manual is brief but it suggests getting the suction cups wet before mounting. This is actually a good idea and helps prevent leaks and makes the suction a tad better. You wouldn't think adding water to your suction cup would be a good idea lol...Wouldn't it make it slide? No it works well and since I suction using my read window for the fork I can actually see the bottom of the suction cups during the ride to make sure they look the same as when I started which they do.

Good: Unit arrived we'll packaged. Suction cups come with protectors. Rear wheel Velcro strap is descent. Suctions are powerful. Bike never touched the car. Known flaw at time of purchase: Only fits old axles. If you have a newish MTB bike with the 15mm axle, you need to order a separate fork mount and alter to fit new mount. ($20). This took a few minutes but I knew that going in. Meh: Aluminum brace flex's when testing the strength of the unit by pulling slightly on the bars. Not a big deal. Sufficiently supports bike but could be stronger. This also allows you to mount it to a curved surface so I guess it's a trade off. Doesn't supply a way to secure the pedals/crank so they don't spin and hit the roof. Extra Velcro would have been nice. Bad: No washers used in construction to spread the load. Suggest adding quarter sized washers if concerned. Imo the hardware would fail before the suction cups. No release valve. Only way to get these things off is to lift an edge and break the seal. Not a big deal if mounting to glass, but would be careful if mounted to paint. Process: Put bike on fork mount while on the ground with protectors on. Secure axle. Lift bike and unit to car while removing protectors. Suction all cups. Lift rear tire and place rear tire cup. Strap rear tire. Done. At destination remove bike by breaking the seal on all cups and dismounting bike. Place unit in trunk. Overall: Legit cool way to transport a bike. No cables, hitch, vehicle alterations etc to mess with. Very low chance of vehicle damage if you are careful. Takes a couple mins tops to get on and off. 1/2 price of the 'name brand' one. Well worth your money.

I can only get two of the suction cups to suck down due to the slope of my roof. Even though I only have two suctions it still holds firm. The only reason why I got this bike rack is because the ones that attach to the trunk started rubbing and damaging my clear coat. I would say the bike holds more secure with this one than the cheaper ones that you attach to the trunk and looks less sloppy.

This thing worked great for the first 2 time. Got down riding for the third and the suction cups on the big part would not tighten down. Bike was not safe on the rack so I had to wait for a friend with a truck to come get me. So disappointed thought I found my solution to transport bike with my car.

That’s an excellent product! I’m a cyclist and ride regularly 3 times a week about 40mils and long rides on weekends of at least 50/100 miles. I bought a new car and decided to get the rockbros as I don’t have a fixed bike rack on the new car (and won’t be getting one :) - and it worked greatly on my last weekend ride! I drove about about 120miles to and back the event at mostly freeway speeds of 60/65mph (did not go over 70mph. I installation was super easy just make sure you clean the mount location and I did follow instructions leaving the location a bit humid after I cleaned it (according to the manual leaving it bit wet helps) had absolutely no problem mounting my road bike on it and it was surprisingly easy to take it off the roff (to be honest a bit too easy as I expected it to be much harder to take it off) but it held firmly throughout the trip and gave me all the confidence I needed no problem! Again great product quality for the price and I’m very satisfied with it. Thanks!

Compared to the Seasucker, this product comes it at a fraction of the cost which makes it a great bargain. A little bit harder to take off than my Seasucker mount but overall pretty much the same. I actually like the fork mount on the Rockbros better but there is one problem. The middle sucker will not stay down and loses air much faster than any other the others. After pumping it up, 5 minutes is all it takes for the white line to show back up. Currently contacting RockBros and see what they can do about this as it seems to be a common issue and a safety concern.

I do very illegal speeds with it and it’s still going strong. Keep a bottle of quick detailer in the car to clean any dirt off of paint where you're going to put the mounts if you care about your paint. Quick detailer is also good for wetting the cups before putting it down.

This is amazing would recommend to anyone !!

Le meilleur achat à faire pour un support à vélo facile à installer et retirer. Je suis à mon 2e le premier à duré 5 ans. Pour le prix c’est un excellent achat ✌🏻

I was actually sceptical about this system and how it would hold but it works fantastically and I have complete confidence in it now. I've even received a few compliments on the setup

Decidí irme con este rack por dos razones, una para mantener la bicicleta los más lejos posible del polvo al pasar por caminos de tierra (la parte trasera del auto siempre se llena de un polvo muy fino, que soloe contamina la horquilla y los frenos), del agua sucia de la lluvia y de un choque. La otra razón es por el espacio de estacionamiento, anteriormente tenía una Chevy tracker del 2000 y entraba en cualquier lugar, pero ahora ya no. Puntos importantes a considerar. + Al principio da miedo girar rápido, ir rápido o simplemente ir. Pero en varios viajes que he hecho principalmente en ciudad con calles llenas de hoyos y terraceria a aguantado muy bien. Incluso, la primera vez que prove el rack lo estrelle contra un cable para secar la ropa, el cable dobló y el rack se mantuvo firme. (aun no lo he probado en carretera, el manual dice que no se debe ir a mas de 120km/h) + Probablemente necesites un adaptador para tu horquilla, en mi caso necesite comprar uno de 15 x 110mm qué tardó como dos semanas en llegar. Si no estás seguro de si necesitas uno, toma un par de fotos de tu horquilla y pregúntale a gemini, chat gpt o simplemente busca en Internet. Toma em cuenta el tiempo de envío por si piensas hacer una salida + Si necesitaste un adaptador probablemente también necesites buscar algo que te ayude a sacar tu eje pasante quick release. En mi caso tengo un Qloc de Suntour qué en ocasiones necesita presionarse para que se libere, no tuve que comprar nada, con una antena de auto que tenía por ahí pude salir adelante, solo tiene que ser capaz de entrar al soporte a través de los adaptadores nuevos y con la punta plana empujas el eje sin que llegue a dañar + La lámina del techo se quedó con dos marcas por las ventosas, una la verás al momento de limpiar con un paño húmedo, la otra espero que nunca la veas, porque a mi me dobló la lámina en dos puntos + Al principio es difícil instalarlo, la mejor forma de hacerlo es que la ventosa central sea la primera que gane un poco de succión, luego haces que las dos laterales ganen un poco de succión, compruebas qué las tres estén completamente pegadas y ahora sí puedes seguir con el proceso de instalación hasta que las líneas blancas no se vean. Si no lo haces así, solo perderás tiempo intentando hacer que la última ventosa gane un poco de succión + No soy de ir a todos lados con la bicicleta montada en el auto, pero te recomiendo medir la altura desde el piso hasta la parte mas alta de la bicicleta estando ya en el auto, principalmente por los estacionamientos techados, incluso algunas plazas o drive thru tienen accesos restringidos por altura

Install is a bit to get used to. once you get familiar with it doesn't take to long. Only thing is its way easier to have it on the ground when putting the fork and axle through but not fully tight. Then remove plastic covers and immediately put on car position and tighten. I've Driven up to 110kms/hr on highway with light wind and going easy on turns and bumps. No issues. We'll see how long it lasts. Also wish the velcro strap for back tire could be something else. Would make me feel abit better but sturdy still. The caps for the axle are just pressure fit in the device and move when trying to fit fork on could have been threaded onto device to prevent this. Also sold separately to fit a specific thru axle. Like really making me pay another $15 for plastic circles. Good product if it lasts as it would be catastrophic if it fails
